52 results about "Terrarium" patented technology

A terrarium (plural: terraria or terrariums) is usually a sealable glass container containing soil and plants, and can be opened for maintenance to access the plants inside. However, terraria can also be open to the atmosphere rather than being sealed. Terraria are often kept as decorative or ornamental items. Closed terraria create a unique environment for plant growth, as the transparent walls allow for both heat and light to enter the terrarium. The sealed container combined with the heat entering the terrarium allows for the creation of a small scale water cycle. This happens because moisture from both the soil and plants evaporates in the elevated temperatures inside the terrarium. This water vapour then condenses on the walls of the container, and eventually falls back to the plants and soil below. This contributes to creating an ideal environment for growing plants due to the constant supply of water, thereby preventing the plants from becoming over dry. In addition to this, the light that passes through the transparent material of the terrarium allows for the plants within to photosynthesize, a very important aspect of plant growth.

Test device and method used for researching root system three-dimensional architecture

The invention relates to a test device and method used for researching a root system three-dimensional architecture. The device comprises a distance determining device and an image collecting device. The distance determining device is used for adjusting the shooting distance and the angle of a plant root system and comprises a guiding ruler with scales and a distance determining rotating platform fixed to one end of the guiding ruler with the scales. The distance determining rotating platform comprises a movable rotating disc which rotates around one end of the guiding ruler with the scales, and a plant placing table is arranged on the movable rotating disc, wherein a plant needing root system observation is placed on the plant placing table. The image collecting device comprises a shooting platform, a digital single-lens reflex camera and a distortionless camera lens, wherein the shooting platform can axially slide relative to the guiding ruler with the scales, and the digital single-lens reflex camera is arranged on the shooting platform. A lens of the digital single-lens reflex camera faces the plant in the guiding direction of the guiding ruler with the scales, and the distortionless camera lens is arranged in front of the lens of the digital single-lens reflex camera. The device and method can accurately obtain a high-resolution image of the root system which is already taken out or the water planting seedling root system in a glass container, and therefore the accurate root system three-dimension architecture is obtained.

Agarose gel substrate cultivated Aglaonema modestum potted plant and preparation method thereof

The invention discloses an agarose gel substrate cultivated Aglaonema modestum potted plant and a preparation method thereof, and particularly relates to the technical field of cultivated Aglaonema modestum potted plant. The agarose gel substrate cultivated Aglaonema modestum potted plant includes a glass container, a high-concentration nutrient layer, a low-concentration nutrient layer and an anti-bacterial layer are sequentially arranged from bottom to top in the glass container, the low-concentration nutrient layer and the high-concentration nutrient layer are closely attached, and the anti-bacterial layer and the low-concentration nutrient layer are closely attached. Gel-cultivated Aglaonema modestum series potted plant are cleaner, a cultivation substrate is free of dust, insects andmolds, and soil and a nutrient solution are not leaked; and meanwhile, in the gel-cultivated Aglaonema modestum series potted plant, the maintenance of the Aglaonema modestum series plant is simpler and does not require subsequent supplementation of fertilizers, the problems of polluting the indoor environment with dust, breeding insects and molds by soil and difficulty in quantitatively controlling the physical and chemical properties such as water and fertilizer conditions and PH value of soil of an existing soil cultivated Aglaonema modestum potted plant are solved, and the problems that the nutrient solution is prone to being splashed and too high or too low nutrient concentration is not conducive to the survival and growth of plants are solved.
